When using Talstar PL Granules, they would have at least a three month residual in the soil. Some vegetables require a longer re-planting waiting period. We suggest you contact the product manufacturer to see what your specific application would require as far as the waiting period. You can reach FMC at 800-321-1362.
Talstar PL Granules are not labeled for earthworms. Earthworms are highly beneficial creatures and you will not find a product on the market that is labeled to eliminate them. Talstar PL Granules are labeled for fleas and ticks and not pine bark beetles. Since pine borers are a type of bark beetle you must apply a product directly to the bark to control the beetles and these products are only available in liquid form, Talstar P. Unfortunately there is no easy solution when it comes to pine beetles. Infected trees should be cut down (before the newly hatched beetles fly out of the trees in the spring/summer) and the wood burned or chipped, while other still healthy trees should be sprayed annually to protect them. Because of the natural boring behavior of the beetle they are protected from topically applied insecticides and systemic insecticides (those injected into the tree or applied as a root drench) have proven ineffective for pine beetle infestations. Healthy trees can be protected before the beetles attack by topically spraying them with a synthetic pyrethroid like Talstar. The tree should be sprayed from the ground to 15 ft up the trunk to prevent future infestations. You should contact your local cooperative extension office to find out the best time to start spraying in your region.
Talstar PL Granules are not labeled to control chiggers. Talstar Pand Onslaught are top-notch professional products and both are labeled for chiggers. Onslaught is micro-encapsulated and will last a little longer on outdoor surfaces which does give it a bit of advantage over Talstar P. Treatments for chiggers should begin in May and could need to continue through the summer as new chiggers move into the area. Treating the entire lawn is of little benefit because chiggers avoid direct sunlight and normally will not infest areas that are mowed or otherwise well maintained. Focus treatment on the unkempt areas of the lawn and lawn edge. You can also use Onslaught to do a barrier treatment around the outside of your home and in your crawl space to stop pests from moving indoors.
Talstar PL Granular Insecticide can typically last 2-3 months after applied and watered in after application.
Talstar PL Granular Insecticide can offer some benefit for ground bees as a prevention.
Ground bees, also known as digger bees, can be very difficult to control no matter what product you use and they most likely will come back to your property year after year unless you do your part to alter your property to make it unfavorable to the bees. Ground bees prefer dry soils with thin grasses so irrigating the area frequently and correcting any issue that causes your grass to be thin will help deter the bees from nesting. In areas where you do not have grass, a layer of mulch will help deter the bees from nesting. Ground bees are solitary bees and are not very aggressive and are known to be a beneficial insect which is why you will not find any products specifically labeled for this type of bee. For current infestations, you would need to use Delta dust in each individual burrow.
The easiest way to determine the correct setting for you needs is outlined below:
If you need to use 3lbs of product per 1,00 sq ft you would add 3 lb of product to spreader, start with a medium setting, then apply product to a 20 x 50 ft area (1,000 sq ft). If you have product left, your setting is too low. If you run out of product, your setting is too high.
We would recommend keeping any reptiles out of the area while you are doing treatments. Once Talstar PL granules have been watered in and the area dries completely, it is safe for them to return back to the area.
Yes regardless of what insect you're treating for, Talstar PL needs to be watered-in in order to activate the active ingredient. Granules can typically last 2-3 months whereas liquids like Talstar P? will last about 30 days maybe more on outside surfaces. For scorpions specifically you would want to go with the Cy-Kick CS? that will sit on top of the surface better than granules and being microencapsulated will last on outside surfaces closer to 60 days. The Talstar PL granules would be great to use for the insects the scorpions feed on though.
